将某个目录下的文件合并成一行，中间用冒号（:）作为分隔符

1、paste

ls lib | sed 's@^@lib/@g' | paste -s -d ":"

2、 tr

ls lib | sed 's@^@lib/@g' | tr "\n" ":" | sed 's@:$@@'

3、xargs

ls lib | sed 's@^@lib/@g' | xargs | sed 's/ /:/g'

4、awk

ls lib | sed 's@^@lib/@g' | awk "{if(NR%`ls lib | sed 's@^@lib/@g' | wc -l`){ORS=\":\"}else{ORS=\"\n\"};print;}"

5、perl

ls lib | sed 's@^@lib/@g' | perl -pe 's/\n/:/;' | sed 's@:$@@'

6、python

#!/usr/bin/env python #coding:utf8 import os def dirList(dir): filelist = os.listdir(dir) allfile=[] for filename in filelist: allfile.append(dir+'/'+filename) return allfile allfile=dirList('lib') pathjar=':'.join(allfile) print pathjar
